Nov 24, 2022 (Nanowerk News) Building on the CRISPR gene-editing system, MIT researchers have designed a new tool that can snip out faulty genes and replace them with new ones, in a safer and more efficient way. Using this system, the researchers showed that they could deliver genes as long...
A sweet new way to print microchip patterns on curvy surfaces
Nov 24, 2022 (Nanowerk News) NIST scientist Gary Zabow had never intended to use candy in his lab. It was only as a last resort that he had even tried burying microscopic magnetic dots in hardened chunks of sugar — hard candy, basically — and sending these sweet packages to...
Novel nanoparticles deliver innovative cancer chemoimmunotherapy
Nov 24, 2022 (Nanowerk News) Some wounds just won’t heal. Infections, diseases like diabetes, and suppressed immune systems often stack up to slow healing. Chronic wounds can last months and lead to anxiety and depression. In the worst cases, they are life threatening. Cost of treatment has soared to $25...
Researchers create green fuel with the flip of a light switch using nanotechnology
Nov 24, 2022 (Nanowerk News) Researchers at Princeton and Rice universities have combined iron, copper, and a simple LED light to demonstrate a low-cost technique that could be key to distributing hydrogen, a fuel that packs high amounts of energy with no carbon pollution. The researchers used experiments and advanced...
A simpler path to better computer vision
Nov 24, 2022 (Nanowerk News) Before a machine-learning model can complete a task, such as identifying cancer in medical images, the model must be trained. Training image classification models typically involves showing the model millions of example images gathered into a massive dataset. However, using real image data can raise...
Non-noble catalyst for hydrogen production
Nov 24, 2022 (Nanowerk News) Hydrogen is a promising future fuel—especially if produced from water—but the necessary noble metal catalysts are rare, expensive, and have insufficient reserves. But now, in a study published in Advanced Materials ("Corrosion-resistant and high-entropic non-noble-metal electrodes for oxygen evolution in acidic media"), researchers from the...
AI tailors artificial DNA for future drug development
Nov 24, 2022 (Nanowerk News) With the help of artificial intelligence, researchers at Chalmers University of Technology, Sweden, have succeeded in designing synthetic DNA that controls the cells' protein production ("Controlling gene expression with deep generative design of regulatory DNA"). The technology can contribute to the development and production of...
Converting waste paper into battery parts for smartphones and electric vehicles
Nov 23, 2022 (Nanowerk News) Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a technique to convert waste paper, from single-use packaging and bags, and cardboard boxes, into a crucial component of lithium-ion batteries. Through a process called carbonisation which converts paper into pure carbon, the NTU researchers...
Sliding nanomechanical resonators based on a graphene substrate
Nov 23, 2022 (Nanowerk News) In a recent study published in Nature Communications ("Sliding nanomechanical resonators"), a research team led by Prof. GUO Guangcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences developed nanomechanical resonators based on a graphene substrate, and made...
Simple semiconductor solutions could boost solar energy generation and enable better space probes
Nov 23, 2022 (Nanowerk News) A 'simple' tweak to perovskite solar cells during the fabrication stage could help to unlock the untold potential of the renewable energy source, claims research from the University of Surrey (Advanced Energy Materials, "Suppressing Interfacial Recombination with a Strong-Interaction Surface Modulator for Efficient Inverted Perovskite...
